Regarding Z Axis delta servo motor stall / overload protection

[joeavaerage]

Hi,
I don't know what exact model servo and drive you have but this comes from the B2 series manual:

If L0003 corresponds to Al003 then that is an under-voltage alarm. This is surprising, I would have expected an over current alarm, AL001, or a following error fault, AL009.

First you need to check the manual for your drive, it may differ from the B2 manual.

It could be that as the load came on, ie the Z axis stalled that the increased current caused the input voltage to sag and thence cause an undervoltage alarm, but that would be unusual.

Here is the model number of z axis drive

Hi,
Ok, it looks like a B2 series servo drive. In which case the fault codes I posted are probably correct.

One possibility that I thought of is that if you de-powered the machine it's not impossible that a fault was logged as the voltage started to decay. It would be the latest fault code logged,
but not necessarily the fault code associated with your crash. Look back through the fault code history.

Hi pal, Sorry for bothering you, but you're the only one diving with me and helping to investigate.

First code is L0003
Second code is L0022.

and will update u till the 5th code later

Thank u.

Hi,
per attached, still does not look like a fault code I would expect from a crash.
